Nielsen • Full time

Jun 2024 - Jan 2026 • 1 yr 7 mos

In my most recent role, I worked on core data and platform engineering for Nielsen’s media analytics products, focusing on performance, scalability, and maintainable architecture. I reworked legacy logic, expanded processing capacity, and contributed to revenue-critical systems that supported large client datasets and evolving weighting requirements. Key Contributions • OOH Component Build: Supported design and launch of an out-of-home (OOH) viewing component by restructuring weighting logic into a more maintainable system architecture. • Performance Scaling: Migrated heavy Java business logic into optimised SQL using JOOQ, increasing data throughput from ~3M to 40M+ records (12× scale). • Platform Ownership: Maintained and enhanced the NPower platform, responsible for ~40% of company revenue, by adding new weight types and client-driven features. • Architecture Simplification: Converted complex legacy pipelines into cleaner, more maintainable SQL/JOOQ workflows that improved reliability and reduced processing time.

Software Engineer Intern

agoda • Full time

Feb 2024 - Jun 2024 • 4 mos

As an Intern, I worked on the Agoda iOS app, contributing directly to customer-facing features and learning large-scale mobile architecture practices. I focused on clean code structure, localisation improvements, and UI performance so new features could scale smoothly for high user volumes. Key Contributions • Feature Development: Built the “Motel Deals” iOS feature end-to-end, delivering functionality adopted by 1M+ users. • Localisation: Adapted date and formatting logic for the Korean market, improving usability for 1M+ users. • Architecture Practices: Applied VIPER and TAGA patterns to separate UI from business logic, which improved modularity and testability. • UI/UX Quality: Designed smoother user flows and interface behaviour to reduce friction and improve engagement within the feature.
